Pearl Jam rocked the stage at Chicago's Wrigley Field on Friday. Following a two hour rain delay, the concert continued until 2 a.m. the next day.

But it was the band's Chi-town native front man, Eddie Vedder, who stole the crowd's heart when he performed this Cubs tribute song, "Someday We'll Go All the Way."

When Vedder began to sing, the fans erupted in cheer.

"We are one with the Cubs. With the Cubs we're in love. Yeah, hold our head high as the underdogs. We are not fair-weather but foul-weather fans. We're like brothers in arms in the streets and the stands."
